THE ASSOCIATED PRESSBATON ROUGE, La. -- Triple-digit heat indexes experienced by three convicted murderers suing officials at the Louisiana State Penitentiary at Angola are similar to the conditions endured by inmates on Death Row in Texas, Mississippi, Alabama and Florida. But condemned prisoners in Arkansas have air conditioning and Arkansas prison policy calls for summertime cell temperatures ranging from 74 to 78 degrees. "We started putting air conditioning in our older units in the late 1970s," said Shea Wilson, spokeswoman for the Arkansas Department of Corrections. Wilson said all state prisons in Arkansas now have air conditioning for all inmates. "I'm glad to know that at least one state recognizes the need to treat prisoners like human beings," said Marjorie Esman, executive director of the ACLU of Louisiana.
